So I'm set on getting Mac long tubes for my v6 do I need a tune will I run lean? With out a tune?
Okay because I have a O/R xpipe right now and I got the mil eliminator for the back two o2 sensors So I don't get a check engine light I was wondering if I can do that with the long tubes,Yes you are gonna need a custom tune. The O2's will read wrong cause of the change in location.
Yea I have the extensions right now. I just wanna know if I will damage the engine by installing long tubes with out a tune? Will I be running lean???If I remember correctly I had to get an extension for the O2 sensor on one of the front ones..
So ill be fine with long tubes and no tune just for a while, once I get my SCT tunnerIt won't be that big a difference in the tune to blow a motor up
